Soil Fumigation Rig in Operation
This video demonstrates how a tractor-based soil fumigation rig operates in the field. The video shows a tractor/applicator operator and an assistant. The operator controls the rig and the assistant makes sure the plastic tarp material is placed properly at the start of each row. The rig has several tanks with fumigant that is pumped through chisels into the soil. The chisels do their work as the tarp seals in the fumigant so it won't volatilize into the atmosphere. The assistant makes sure a wheel overlaps the tarp being applied with the tarp already put down in the next row. An adhesive is applied from another tank on the tractor to glue the tarp sections together under the wheel as it rolls down the row. The process moves pretty quickly as you can see from the video.
